The importance of geographical information systems in urban and landscape planning: A bibliometric analysis Celik, Kadir Tolga; Sekeroglu, Ahmet Since the 1970s, Geographic Information Systems (GIS) have gained increasing recognition in the literature, drawing the attention of numerous scientific disciplines, particularly within technical and environmental sciences. What initially began as computerized map production in the 1970s has evolved with advancements in computer processing power and capacity, supported by various software packages. This study aims to reveal the general tendencies in research studies conducted in the fields of urban planning, spatial planning, and landscape planning. To identify these trends, a bibliometric analysis was conducted by examining literature on studies published worldwide, including Turkiye. For this purpose, 2,354 research and review articles published between 1990 and 2022 and indexed in the Web of Science database were analyzed using VOSviewer software, which is suitable for scientific mapping and bibliometric analysis. The analysis focused on the most frequently published journals, highly-cited authors and countries, collaborative authorship relationships, and the most cited authors, journals, and research topics in Turkiye. As a result, it has been observed that, considering the emergence of modern GIS concepts in the late 1970s and subsequent development based on spatial data from the 1980s, studies in the fields of Urban and Regional Planning, Urban Design, and Landscape Architecture have gained momentum since the 1990s. Research establishing the relationship between GIS and planning in Turkiye has been increasing since 2004, with the primary focus of these studies being categorized into three clusters: site selection, spatial mapping, and mathematical modeling.

The Role of Conscious and Unconscious Proprioceptive Sensation in Unstable Postural Balance: A Cross-Sectional Study

The Role of Conscious and Unconscious Proprioceptive Sensation in Unstable Postural Balance: A Cross-Sectional Study Payas, Ahmet; Kurtoglu, Erdal; Varol, Busra Kepenek; Batin, Sabri; Kararti, Caner; Koc, Ali; Ucar, Ilyas Objective: Proprioception is the capacity to perceive the position of any body part, either consciously or unconsciously. This sense, in conjunction with the visual and vestibular senses, helps maintain postural balance. This study explores the relationship between postural balance analysis outcomes and proprioceptive sense tractography data. Materials and Methods: Sixty-two healthy individuals were categorized into two groups based on postural balance analysis: the unstable posture group and the stable posture group. Postural sway test measurements, such as sway area, track length, velocity, Romberg quotient, lateral sway, and anteroposterior sway, were recorded for both groups on fixed and moving surfaces over 20 seconds. Using the DSI Studio program, tractography of the proprioceptive sensory pathways was conducted on participants using brain diffusion tensor images (DTI). IBM Statistical Package for the Social Sciences (SPSS) 23.0 software was employed for statistical analysis, with a p -value <0.05 considered statistically significant. Results: Tractography of the unstable posture group revealed increased mean diffusivity (MD) and radial diffusivity (RD) in the brain white matter, superior cerebellar peduncle, and middle cerebellar peduncle, while axial diffusivity (AD) values decreased (p<0.05). There was a notable correlation between the sway area in the unstable and eyes -open positions and the fiber count and fiber percentage in the right inferior cerebellar peduncle. Conclusion: The data suggest impairments in the pathways responsible for carrying unconscious proprioceptive sensations in individuals with unstable posture.

Examining The Problems Posed By Classroom Teacher Candidates According to Mathematical Process Skills

Examining The Problems Posed By Classroom Teacher Candidates According to Mathematical Process Skills Sayin, Volkan; Orbay, Keziban In mathematics teaching, problem posing is an expected outcome for students. It is important for future teachers to be able to pose problems effectively when implementing the mathematics curriculum. This study aimed to examine the problems posed by classroom teacher candidates based on their mathematical process skills. The Problem Posing Test, used as a data collection tool, was was developed based on four objectives within the domain of measurement learning. In this quasi -experimental study, both the experimental and control groups comprised 25 volunteer classroom teacher candidates each. Analysis of the problems posed by teacher candidates was carried out according to the conceptual framework created by the researchers. The analysis revealed that classroom teacher candidates struggled with mathematical communication, association, and reasoning skills. Specifically, it was observed that they often wrote mathematical units incorrectly or incompletely, overly relied on verbal representation, failed to make interdisciplinary connections, and frequently posed problems requiring analogy -based reasoning. After instruction in problem posing, teacher candidates in the experimental group demonstrated improved mathematical process skills. Future studies should examine the problems posed by teachers or teacher candidates across different grade levels to assess their mathematical process skills.

Effects of lercanidipine on traumatic spinal cord injury: an experimental study

Effects of lercanidipine on traumatic spinal cord injury: an experimental study Turk, Caglar; Bahadir, Sinan; Camlar, Mahmut; Gurel, Cevik; Buhur, Aylin; Kuscu, Gokce Ceren BACKGROUND: Spinal cord injury is a devastating trauma that leaves survivors at risk for several medical complications throughout their lives. Lercanidipine, a third-generation calcium channel blocker, possesses anti-apoptotic, anti-inflammatory, and antioxidative properties. This study aimed to evaluate the neuroprotective effects of lercanidipine in an experimental spinal cord trauma model. METHODS: Twenty-one Wistar rats were randomly assigned to three groups. Group 1 (G1) underwent laminectomy. Group 2 (G2) were subjected to trauma following laminectomy. Group 3 (G3) were exposed to trauma following laminectomy and treated with lercanidipine. Lercanidipine was administered intraperitoneally for seven days. Histopathological and immunohistochemical evaluations were conducted. RESULTS: Regarding Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining, there was no significant difference among the groups. However, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappa B) levels were significantly different across the groups. G2 had significantly higher NF-kappa B levels compared to G1 and G3. CONCLUSION: Lercanidipine, a third-generation calcium channel blocker, is effective against inflammatory responses induced in spinal cord injury. Further studies are required to determine its capability in preventing apoptosis or improving functional recovery. To the best of our knowledge, this study is the first in the literature to examine the neuroprotective effects of lercanidipine on spinal cord injury.
